European regulations have set limits for particulate matter (PM) concentrations due to health concerns. However, PM's complex composition and varying properties suggest that mass concentration alone may not fully reflect its health impact. Oxidative potential (OP), which measures PM’s capacity to induce reactive oxygen species in biological media, is emerging as a promising indicator for air quality regulations. This study explores OP levels across 43 locations in ten European countries, aiming to evaluate the added value of OP in terms of PM reactivity and health-related properties. The research supports the introduction of OP measurements in upcoming European Directive revisions, expected within two years.
